Brilliant Diamond

The best of all is generally the round brilliant cut, as it reflects about 5-6% of all light entering it. This is true for most stones, Diamonds, Cubic Zirconias & Moissanites.
The reason for this, is that from MOST angles, the light entering will pass through a similar amount of gemstone material (for example Carbon in the case of a diamond), and as such, the beams of light that enter, have a good chance to come out from the table & shoulders of the gemstone (kite facets etc), at an optimal rate, there is a certain mathematical beauty in how the design of the modern round brilliant was originally conceived. Please note, a "PERFECT" round brilliant cut does not actually exist, as NOWHERE in the original plans for the modern round brilliant cut diamond, put down by Tolkowski when he created this cut, was there any mention of any GIRDLE. The "perfect" diamond should have knife edge girdle according the original specifications, this will however be very hard to find, so the best bet for the modern consumer is to ensure you have the best crown angle, pavillion angle, and crown + pavillion depth, in order to maximise the brightness of the stone. If you have further questions, feel free to ask.

This really depends on size & taste. Generally speaking, if the diamond is smaller, 4 claws is suggested, if the diamond is large (about 0.70ct+) then people often suggest 6 claws, for the sake of safety, 6 claws is definitely superior.

The most common & simplest is generally having some engraving done on the inside of the band. This is fairly simple & not overly expensive, also fairly quick.
